Regression toward the mean is a widespread phenomenon in statistics and may adversely affect researchers' substantive interprettion of findings. Therefore, it is worthwhile to evaluate the extent of regression toward the mean as a part of many applications of regression analysis. One way to assist with such an evaluation is with a Galton squeeze diagram (Campbell & Kenny, 1999), which provides a quick visual summary of regression toward the mean. This paper demonstrates a novel application of SAS SGPLOT to create publication?]ready Galton squeeze plots.
